RADIATOR GAP.

Application filed November 11, 1922. Serial No. 600,414.

To all whom, it may concern:

Be-it known that I, ROBERT C. Rossnnn, citizen of the United States, residing at Dal las, in the county of Dallas and State of Texas, have invented certain new and useful 1 thus defeating the usual attempts. to steal the cap and any ornament or motor-meter it may support.

An important object of the invention is to provide a ring and sleeve combination which will co-operate with the filling collar of a radiator in such a manner as to prevent either upward or downward displacement of" the ring, whlle at the same time permittlng rotation of said ring, unless the fastened.

A further object of the invention is to provide a cap comprising two main members, one of which when screwed into the collar same is cannot be removedwithout the aid of the.

other member, together with means for connecting the members together when itis desired to legitimately remove the cap. A. still further object is to render the meansof connection between the members more difiicult.

to effect, after the cap has once been placed in position.

Another object of the invention is to mount one ofthe members sothat it may be freely rotated without removing the cap and to mount on sand member the ornamental arms, ornaments, motor-meter and quick A construction designed to carry out the invention will be hereinafter described together with other features of the invention. p The invention will be more readily understood from a reading of the following speci fica-tion and by reference to the accompanying drawings, in which an example of the invention is shown, and wherein:

Fig. 1 is a plan view of a cap constructed in accordance with my invention,

' Fig. 2 is a front elevation of the same,

Fig. 3 is a rear elevation,

Fig. 4 is an enlarged vertical sectional view,

Fig. 5 is an enlarged sectional detail of the plug receiving parts,

Fig. 6 is a detail of the plug, 7

Fig. 7 is an enlarged elevation of the sleeve, and

' Fig. 8 is a sectional detailof the ring.

In the drawings the numeral 10 designates a cylindrical sleeve having itslower portion reduced and provided with external screw threads 11 above which the sleeve has an overhanging annular shoulder 12 as is shown in Figs. 4 and 5. At its upper end the sleeve has an outwardly directed annular flange 13. A ring 14 surrounds the upper portion of the sleeve and has its lower edge terminating flush with the shoulder 12. The ring projects above the sleeve, but is reamed out to form an annular shoulder 15 on which thefiange seats. The flange has its upper surface flush with the upper edge of the sleeve, thus forming an annular seat16 for a gasket 18 which surrounds an upstanding lip 17011 the inner edge of said sleeve.

A boss 19 is formed on the rear side of the ring and-supports a pair of spaced ears 20 between whicha hinge lug 21 is received. A pintle 22passing thru the parts 20 and 21 hinges them together. The lid 23 has a general frusto-conical shape and is hollow. The lid has an annularapron 24- on its lower edge fitting in the upperside of the ring and bearing upon the gasket 18.

The ring is also provided with bosses 25 on each side of its front in which a transversely elongated bail 26 is pivoted. The lid has a lug 27 on its front over which the bail is adapted to engage and fastens the apron down upon the gasket, whereby a vater-tight joint is had. To open the lid it is merely necessary to swing the bail forwardly and swing the lid upwardly upon its hinge.

The lid has a central opening 28 normally closed by acompression plug 29, which may be of any approved construction and which is removed when it is desired to mount a motor-meter or ornament on the lid. The ring is provided at right angles to the lugs 20 and 27 with integral balls 31 on their outer ends. However it is to be understood that the arms may be dispensed with and any suitablefastening means for the lid may be used.

The sleeve is screwed into the flange 32 of aradiator filling collar 33'such as is common on automobile radiators. The upper edge of thefl'ange 32' receives the shoulder 12 of the sleeve and also the lower edge of the ring 14- and the latter is free to rotate thereon around the sleeve, being held against upward displacement by the flange 13'and shoulder 15; In order to connect the ring and sleeve as a unit a set screw 34 is threaded into an opening 35 in the boss 19 and engaged in a sump 36 in the sleeve. When so connected the ring will rotate the sleeve, but when the screw is removed the ring will rotate without turning the sleeve. When the screw is removed the opening 35 is filled with a hollow plug 37 which is wedged therein, but does not engage the sump.

It will be seen that when the sleeve is screwed into the flange 32 as far as it. will be the arms 30' may extend at an angle to the front of theradiator. hen the screw 34 is removed and the plug 37 inserted in the opening 35, the ring l t and sleeve 10 are disconnected. The ringand arms may be thus freely rotated so that the arms are al'ined with the front of the radiator or may be turned to any position. Further one attempting to remove the cap could not turn the sleeve. unless some connection between the ring and sleeve was made thru the opening 35.

hen it is necessary to remove the cap a small hole is drilled in the end of the plug 37 and a hook inserted by which the plug may be pulled out., The ring is then rotated until the sump 36' is visible and a screw is screwed into the opening 35 and engaged in the sump, whereby the ring and sleeve are connected and the sleeve may be unscrewed by rotating the ring. This is accomplished without removing the radiator or disturbing any other part of the car. hen it is desired to fillthe radiator it is merely necessary to swing the bail 2G forwardly and raise the lid 23. After the filling; operation the lidis swung down and the bail swung upwardly and sprung over the lug 2? whereby the gasket 18 is compressed by the apron 24 and a water-tight closure is had.

A structure of this nature permits of va rious changes in the size and shape of the various parts and such changes together with modifications may be made within the scope of the appended claims.

lVhat I claim is:

1. In a radiator cap, a sleeve adapted to be attached to the filling collar of a radiator, a ring mounted to rotate on the sleeve, a filling lid and fastening therefor mounted on the ring, removable means for fastening the ring and sleeve together, and a plug for filling the opening left by the removable means.

2. In a radiator cap, a sleeve adapted to be attached to a radiator filling collar, a ring rotatably confined on the sleeve, a gasket carried by the sleeve within the ring, a lid hinged on the ring and engaging the gasket, means on the ring fastening the lid in its closed position, and a screw passing thruthe ring and engaging in the sleeve for connecting the ring and sleeve whereby the sleeve may be turned by the ring, the screw being removable whereby the ring is free to rotate.

3. In a radiator cap, a sleeve adapted to be attached to a radiator filling collar, a ring rotatably confined on the sleeve, a gasket carried by the sleeve within the ring, a lid hinged on the ring and engaging the gasket, means on the ring fastening the lid in its closed position, a screw passing thru .the ring and engagingin the sleeve for connecting the ring and sleeve whereby the sleeve may be turned by thering, the screw being removable whereby the ring is free to rotate, and a plug for filling the opening in the ring left when the screw is removed.

4. In a radiator cap, a sleeve adapted to be attached to a radiator filling collar, a ring rotatably confined on the sleeve, a gasket carried by the sleeve within'the ring. a lid hinged on the ring and engaging the gasket, means on the ring fastening the lid in its closed position, a screw passing thru the ring and engaging in the sleeve for connecting .the ring and sleeve whereby the sleeve may be turned by the ring, the screw being removable whereby the ring is free to rotate, and a hollow plug for filling the opening left when the screw is removed and adapted to be removed by suitable tools to permit the reinsertion of the screw.

5. In a radiator cap, a sleeve having e\= ternal screw threads at its lower end and a flange at its upper end, a ring rotatably surrounding the sleeve and having a shoulder receiving the flange. the screw threads of the sleeve projecting below the ring and adapted to engage in a radiator filling collar, the ring being located to rest on the ing in the opening of the ring but free from the sump of the sleeve whereby the ring is ,free to rotate.
